Can I add a manual DNS entry for an internal mail server instead of the ESA going and doing a reverse lookup? I would like to bypass DNS lookups for a particular server.
thanks

Hi,
ESA does not have an option to add manual DNS entries.
The reverse DNS lookups are performed for all connections for reporting purposes, however you can control the action taken on reverse dns lookup failures.
Thank You!

Hello,
We have an article that goes over adding local PTR records on the ESA. It is normally used for cluster communication, but may be useful for your case.
Create or join ESAs to a cluster without PTR records
Thanks!
